Powerful Data Preprocessing with the Enhanced Pipeline Engine
GreptimeDB v0.15 introduces significant enhancements and refactoring to its Pipeline Engine. This article explores these recent capabilities—highlighting native pipeline integration with Prometheus Remote Write and Loki Push API. Using hands-on examples, we demonstrate how users can flexibly preprocess metrics and logs data in real time, implement custom field transformations with VRL, and manage dynamic table creation with table hints. Whether you're looking to streamline your observability workflows or unlock new levels of data customization, these features in GreptimeDB's pipeline provide an effective and scalable solution. All the techniques described here remain applicable in v0.16 and above.
